Hydrogen only has 1 electron.
Four.
Only one valence electron.
HCN, hydrogen cyanide, has a total of 10 valence electrons. Hydrogen contributes 1 valence electron, carbon contributes 4 valence electrons, and nitrogen contributes 5 valence electrons.
Two electrons will fill a hydrogen's outer, or valence, shell.
Hydrogen has only one valence electrons.
Four.
14 total electrons. 5 valence electrons.
There are three valance electrons. These are the electrons in the outer shell if it is not full.
One. A hydrogen atom contains only one electron, and it is a valence electron.
A hydrogen atom has 1 valence electron.
It's called a valence electron, and there's 1 for a hydrogen atom
5
Hydrogen chloride (HCl) has 7 valence electrons. Hydrogen contributes 1 valence electron and chlorine contributes 7 valence electrons.
Only one valence electron.
1
Hydrogen doesn't really have a valence shell. It has one electron only.
The valence of hydrogen is 1. This means that hydrogen has one valence electron, which allows it to form one covalent bond with other atoms.
